Probably, during the formation of spherical Au nanocrystals, PVP or PAM can be selectively adsorb on certain crystal planes of Au nanocrystals by the complexing effect between N or O with Au atom, thus leading to the different growth rates at different crystal planes of spherical Au nanocrystals and resulting in the formation of faceted Au nanocrystals and Au nanoplates.

研究表明，多面体和片状Au纳米晶是由球形Au纳米晶转变而来，这个转变是由于在球形Au纳米晶的形成过程中，PVP和PAM借助于其特有的N原子和O原子吸附到Au纳米晶的Au原子上，造成了晶体不同晶面生长速率的差异而导致的结果。

Among these particles, the prismy crystals and regular cubic crystals were specifically identified as sulfates of Ca and NaCl from sea salt respectively. But the spherical, fractal and sheet-like particles have very diverse compositions. b The composition of fractal particles is the most complicated, and that of spherical ones is less complex.

其中，棱柱形长棒晶粒和规则的立方形晶粒具有特定的组成，分别为钙的硫酸盐和来自海洋的NaCl晶体，而球形、块状和片状颗粒元素组成变化较大。b块状颗粒的化学成分最为复杂，球形颗粒其次。
